Phlox subulata also known as Creeping phlox, is one of the most recognized herbaceous perennial plants. This vigorous, spreading and sun-loving perennial plant can grow only 6” high but spreads to 24” wide. It is native to dry, rocky places and open woodlands of the Appalachian mountains. Plants will tolerate deer, drought and hot exposure, and erosion but good drainage is essential, and watch out for rabbits. Flowers will open in April-May on top of foliage mats with similar look to moss, where it gets its common name - moss phlox. After flowering we recommend to cut back slightly the vegetation to promote denser mat-forming. As a ground cover Moss phlox is most used in sunny areas along rock walls, edgings, rock gardens and slopes.

Growing information

Phlox: Bare Root or Potted Plant Perennial

How to Plant

Planting Bare Root Plants:

Select a location in full sun with a well amended soil that is evenly moist. Make sure there is good air circulation.

Prepare the bed by turning the soil under to a depth of 6-12, inches removing any debris, and lightly raking as level as possible.

The addition of organic matter (leaf mold, compost, well-rotted manure) benefits all gardens and is essential in recently constructed neighborhoods.

Dig a hole deep and wide enough to accommodate the bare root.

Set the plant such that the crown is at or just slightly below the ground level. Allow roots to fan out from the crown at around a 45 degree angle. Roots should spread out separately, like stretched fingers, from the crown, and not bunch up. It may be helpful to build a cone-shaped mound of soil in the bottom of the hole and spread the roots around it. It is important to set the roots such that the crown is roughly level with the ground.

Cover the roots with soil and tamp down firmly to get rid of air pockets. Fill the soil to just below the crown, where the top growth and leaves will emerge. Make sure all the roots under the crown are in good contact with the soil.

Water well to fully saturate the roots and soil.

Wait until new growth starts to appear before applying a layer of mulch.

Planting Potted Plants:

Select a location in full sun with a well amended soil that is evenly moist. Make sure there is good air circulation.

Prepare the bed by turning the soil under to a depth of 6-12, inches removing any debris, and lightly raking as level as possible.

The addition of organic matter (leaf mold, compost, well-rotted manure) benefits all gardens and is essential in recently constructed neighborhoods.

Plant on a cloudy day or in late afternoon to reduce transplant shock.

Dig a hole for each plant large enough to amply accommodate the root ball.

Unpot the plant and gently loosen the root ball with your hands to encourage good root growth.

Place the top of the root ball even with the level of the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand.

Use the plant tag as a location marker.

Thoroughly water and apply a light mulch layer on top of the soil (1-2 inches) to conserve water and reduce weeds.

How to Grow

Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their germination.

Mulches also help retain soil moisture and maintain even soil temperatures. For perennials, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.

Careful watering is essential in getting perennials off to a good start. Water thoroughly at least once a week to help new roots grow down deeply. Soil should be damp at about 1 inch below the soil surface. You can check this by sticking your finger in the soil. Water early in the morning to give all leaves enough time to dry. One inch of rain or watering per week is recommended for most perennial plants. You can check to see if you need to add water by using a rain gauge.

Until plants become established, some protection from extreme winds and direct, hot sunlight may be necessary. Good air movement is also important.

After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer, as higher rates may encourage root rots.
